Equipped with high power Brushless DC motor. Maintenance-free due to no brush. Energy production is more efficient than brushed DC motor because of no friction loss caused by brushes, enabling to lower amperage for reduced heat production and increased work amount on a single full battery charge. Thanks to the very efficient energy production of the BLDC motor, work amount on a single full battery charge is increased. Lifetime work amount of a battery is increased, reducing the battery cost. Use of BLDC motor lowers heat production; the temperature rise at the housing surface can be recessed, even in hard industrial applications requiring a continuous long operation. Variable Speed, Electric Brake, Orbital Cutting, Bayonet Shank, Dust Collecting and Built-In Job Light. Battery and charger sold separately. Dust nozzle is sold separately.
